Marshall caught 102 receptions for 1,134 yards and 27 touchdowns, while leading the AFL with 1,901 yards and six touchdowns as a kick returner.[2] His efforts attracted the attention of the Chicago Bears of the National Football League, who welcomed him to one of their practice sessions on June 6, 2007. He competed for a spot as a starting wide receiver against Rashied Davis, who coincidentally played in the Arena League before signing with the Bears.[2] Marshall was released by the Bears on August 27, 2007.[3] He signed with the Kansas City Chiefs on July 23, 2008 but was released five days later.[4]
